16 Over the coming week we will be making snapshot builds of the
17 i-scream central monitoring system from the CVS repository.
18 These builds will have quite a few changes from the downloads
19 currently available (a document detailing them will be
20 released later on), so please give them a whirl. We would be
21 grateful if you <a href="mailto:dev@i-scream.org">contacted</a>
22 us with any questions or bugs.<br><br>
23 The downloads will be available on our snapshot server :-<br>

30 Work has now been finished on a new ihost written in C. This has
31 been in the pipeline for a long time, and we're glad to finally
32 see an efficient native host! Credit goes to our new developer
33 <a href="/who.shtml">Pete</a>. Until we update the downloads
34 pages you can download the new ihost
35 <a href="http://snapshots.i-scream.org/ihost/ihost-1.0rc1.tar.gz">

41 We've finally put the finishing touches to the new
42 <a href="http://rrdtool.eu.org">RRDtool</a> based graphing system.
43 It's working well, and has done away with the MySQL database
44 backend which took up far too many resources. This new system
45 generates the graphs in a more realtime nature, allowing more
46 flexible graphs to be generated. This is currently only available
47 through <a href="http://cvs.i-scream.org/cms/source/reports/rrdgraphing/">
48 CVS</a>.

60 The alerting section of the i-scream central monitoring system
61 now makes full use of an externally developed IRC bot for it's IRC
62 connectivity. To find out more about this IRC bot, please visit

69 Java ACL (Access Control List) code has been added to the util
70 package of the i-scream server. This code will ultimately allow
71 the server to be more secure when exposed to the Internet. More
72 details can be found <a href="http://www.cs.kent.ac.uk/people/staff/tdb/#acl">
73 here</a> on the author's website.

83 A variety of <b><a href="screenshots">screen shots</a></b> from the

85 page provides a static example of what the i-scream reports (alerts,
86 historical graphs, and live data) could look like on a production system.

105 Work is continuing, in conjunction with the new ihost, to extend
106 the range of i-scream's monitoring. Currently we are adding new
107 features to more accurately monitoring memory and swap usage,
108 along with more disk statistics. We are also planning to improve
109 the rather basic service monitors which are currently in place.
110 There are also many more subtle changes that need to be made to
111 improve the reliability and usefulness of i-scream's monitoring.

115 <b>Server security</b><br><br>
116 Security was something mostly overlooked in the original stage
117 of this project (due to the academic nature of the work). However,
118 once in production use this has become an issue, and is being
119 addressed. Initially the plan is to lock down the external points
120 of access (TCP & UDP) in the server to specific hosts. In the
121 longer term, encryption of data would be nice, but would take a
122 lot more time and work.

127 <a href="screenshots/"><img border="0" src="screenshots/thumbnail-winhost-main.gif" width="100" height="62" align="right"></a>
128 The i-scream system is being tested and developed within the
129 Univeristy of Kent Computer Science department by the Systems
130 Group. This has led to many bug fixes and minor feature
131 enhancements, and will hopefully help to aid the long term
132 development of the system.

139 <a href="screenshots/"><img border="0" src="screenshots/thumbnail-reports-raptor-latest-misc.gif" width="100" height="104" align="left"></a>
140 The i-scream Distributed Central Monitoring System started off as
141 a final year project for a group of <a href="http://www.cs.kent.ac.uk">
142 Computer Science</a> students at the <a href="http://www.kent.ac.uk">
143 University of Kent at Canterbury</a>, UK. The project was completed at
144 4pm on 29 March 2001. It consisted of five lever-arch folders containing
145 mostly source code and documentation. The CVS repository was tagged to
146 signify this even, however, the project is still being developed by the
147 <a href="acknowledgements.shtml">core development team</a>.

150 <p align="justify">
151 <a href="screenshots/"><img border="0" src="screenshots/thumbnail-ihost-main.gif" width="100" height="51" align="right"></a>
152 As can be seen in our &quot;<a href="/probdomain.shtml">problem domain</a>&quot; document, the project
153 was aimed at the UKC Computer Science department, and as such
154 we believed that a demonstration to the &quot;customer&quot; was important. The
155 feedback from our demonstation was more positive than we had
156 anticipated. We believe that the system may now be of interest
157 to anybody who wishes to monitor a number of machines on their
158 network using a central configuration. The i-scream central
159 monitoring system is now being used by the UKC Computer Science
160 department, and their feedback is being used to further improve
161 the product.

165 <a href="screenshots/"><img border="0" src="screenshots/thumbnail-conient-config.gif" width="100" height="48" align="left"></a>
166 The name <i>i-scream</i> arose from a meeting whereupon one member
167 of the <a href="acknowledgements.shtml">development team</a> felt a strange urge to draw an ice cream on the discussion board.
168 It later became apparent that we had no name for our project (other
169 than 'The Project'). It seemed only natural to name our project after
170 the ice cream that had been oh-so-randomly drawn on the white board.
171 Copyright issues immediately ruled out anything involving Mr Whippy,
172 so we had to settle for <i>i-scream</i>. And thus, we were left with a cunning
173 play on words - it still sounded like <i>ice cream</i>, yet also
174 served as a functional description of our system - namely, one which
175 screams at somebody if something has gone wrong...
